TPA3007D1中文资料6.5W 单声道 D 类音频功率放大器 (TPA3007)数据手册TI规格书

描述 Description

The TPA3007D1 is a 6.5-W mono bridge-tied load (BTL) class-Daudio power amplifier with high efficiency, eliminating the need for heat sinks. The TPA3007D1 can drive 8- speakers with only a ferrite bead filter required to reduce EMI.The gain of the amplifier is controlled by two input terminals, GAIN1 and GAIN0. This allows the amplifier to be configured for a gain of 12, 18, 23.6, and 36 dB. The differential input stage provides high common mode rejection and improved power supply rejection.The amplifier also includes \"de-pop\" circuitry to reduce the amount of pop at power-up and when cycling SHUTDOWN.The TPA3007D1 is available in the 24-pin TSSOP package (PW) and does not require an external heat sink.
